A lyrical science fiction mystery wrapped in a LGBTQ love story that bends space, time, myth, and science—perfect for fans of Octavia Butler and Emily St. John Mandel.

“Dreamy and mysterious and nearly impossible to pin down.” —Paste Magazine

Sol has disappeared. Their Earth-born wife Lumi sets out to find them but it is no simple feat: each clue uncovers another enigma. Their disappearance leads back to underground environmental groups and a web of mystery that spans the space between the planets themselves.

Told through letters and extracts, the course of Lumi’s journey takes her not only from the affluent colonies of Mars to the devastated remnants of Earth, but into the hidden depths of Sol’s past and the long-forgotten secrets of her own.

Set in a future where climate change has reduced the Earth to a playground for the wealthy, The Moonday Letters is part eco-thriller, part space-age epistolary, and a queer love story between two individuals from very different worlds.
